Hi, I add this plugin into my project and set the start capture funtion when the game starts. It will crash and the callstack is below.

but If the ShowUI option is turned off, there is no problem.

Hi this is an engine bug that is happening inside the engine when you try to read from a Dx12 texture. either upgrade your unreal version or use dx11 / vulkan . Let me know if you had any other questions !

Thank you. That problem is solved
